PPB Program/Erase Algorithm
Note
The bank entered during entry is the active bank. Take for example the active bank is BA0. Any reads in BA0 will result in status reads of the
PPB bit. If the user wants to set (programmed to “0”) in a different bank other than the active bank, say for example BA5, then the active bank
switches from BA0 to BA5. Reading in BA5 will result in status read of the bit whereas reading in BA0 will result in true data.
